Summary

A novel method for measuring tensile strength of heat-setting gels is described and is applied to whey protein gels. Contributions made by β-lactoglobulin and α-lactalbumin individually to the tensile strength of the gel are calculated. The tensile strength can be found from power law equations related to concentration of α-lactalbumin and β-lactoglobulin in whey protein mixtures.
